Ruby tail call optimization
Webb10 sep. 2014 · Tail Call Optimisation refers to a form of optimisation, or program transformation commonly used in programming languages with optimising-compilers. It optimises tail-recursive functions by transforming (or rewriting) them in loops, which avoids the overhead of recursive function calls. Webb18 aug. 2010 · 9. Although modern compilers MAY do tail-call optimization if you turn on optimizations, your debug builds will probably run without it so that you can get stack traces and step in/out of code and wonderful things like that. In this situation, tail call optimization is not desired. Since tail call optimization is not always desirable, it doesn ...

In #6602, there was the opinion that tail calls are rare in Ruby, but that may also have to do with the fact that they are not optimized. So to some extent, it's a chicken and egg problem. What usually happens is that users write programs and run them.
Webb8 dec. 2024 · Tail call optimisation (or TCO) is a fascinating optimisation technique that is commonly discussed in the functional programming community, because of it’s importance in the implementation of efficient recursive algorithms. However, it is often overlooked when discussing other programming languages.
